IMPROVEMENT IN METALLIC CARTRIDGES.

SpccUcaft/ion forming part of Letters Patent No. 99,666, dated February 8,1870.

To all whom it may concern Be it known that I, EDWIN GOMEZ, of the city and State ot' New York, have invented an Improvement in Cartridges for FireArms, and I do hereby declare the following to be a full, clear, and exact description of the said invention.

In Letters Patent No. 21,253, granted August 24, 1858, a cartridge is shown in which the explosive material is spread upon a strip of paper, and the same is rolled n p and introduced within a separate paper case, that is tied around the ball, and folded together at the back end, to retain the said roll of explosive paper. This character of cartridge was not well adapted to breech-loading fire-arms, because the paper wrapping or case has to be torn open, or else penetrated by the iiash of the cap.

The nature ot' my present invention consists in a new means for attaching the roll of paper and explosive material to the ball, and combining with the said ball and roll of explosive material and paper a metallic cartridgecase, whereby this character of cartridge is especially adapted to breech-loading fire arms, as the metallic case prevents the roll ot paper being detached, or the powder being shaken ont in handling', and acts to prevent the escape of gases at the breech, and contines the.

Hash of the fulminate. The powder between the coils of paper is to be consumed the moment the ball leaves the muzzle. This, Ind, lessens the noise of the explosion very materially.

I have shown in the accompanying drawing, in Figure l, a section of a large-sized cartridge, longitudinally, and in Fig. 2, a portion of the strip of paper or similar material is represented. A

The ball is to be of any desired size and shape. I have shown the ball c with a central rear projection, b, to which the paper is attached.

The strip of paper or other material is cut out, of a width corresponding to the length ot' the roll or cartridge, when wound up, as seen at c c, and toward one end the paper is left wider, as at b b', in order that the same may extend up around the projection b, and receive a windin g of string or other material, to attach it to the ball, as seen in Fig. l.

The strip of material may be coated with varnish, to render the same water-proof, and

. the coat of explosive material, such as named in my aforesaid patent, is to be spread upon the strip, and it may be caused to adhere slightly to the surface by the same being spread upon the surface while the varnish is in a slightly adhesive condition, from not being entirely dry, or from being softened by a slight heat, or otherwise.

The powder is retained by the said varnish, so that it does not shake ont from between the paper.

By this manner the roll of explosive material is easily and firmly attached to the ball, and a separate case is dispensed with for connecting the roll and ball.

rIhe sheet-metal cartridge-case c is made with the usual flange, i, so that it canbe drawn out from the barrel of the breech-loading 1i rearm, and fulminate is to be introduced either inthe rim or toward the middle of the cartridge, in any usual manuel'. I' have shown the bridge o and fulminate r for a central re.

The roll of paper and explosive material may be perforated or pierced with holes, so as to give opportunity for the deton ation to'reach the explosive material.

If desired, a coil of tape-fuse, such as in Letters Patent 34,057, granted January 7, 1862, may be inserted in the metallic case, with the end, or a perforated portion of the fuse, contiguous to the fnlminate, to insure the explosion ofthe cartridge; and, if desired, gunpowder or other explosive material may be introduced in the metallic case, in addition to the coil or roll aforesaid.

What I claim, and desire to secure by Letters Patent, is-

1.A sheet of paper, or similar material, coated with an explosive compound, and rolled or coiled, and inserted into and combined with a metallic cartridgecase, so as to separate the powder by the intervening sheet, and retain the powder from shaking out, by said sheetmetal case, as and for the'purposes set forth.

2. The cavity at the end of the coil or roll of paper, for the projectile, formed by the wider portion b ofthe paper containing` the explosive material between its layers, substantiall y as and for the purposes specified.

In witness whereof I have hereunto set my signature this 10th day of September, A. I).
